CLoTHl-:s-WRINGER.

SPECIFICATION forming part of Letters Patent No. 278,966, dated June 5, 1883,

Application filed March a, 188s. (Model.) v

To a/ZZ whom it may concern:

Be it known that I, HENRY C. HOPKINS, a citizen of the United States, and a resident of Covington, in the county of Kenton and State of Kentucky, have invented certain new and useful Improvements` in Clothes-Vringers, of which the following is a specification.

My invention relates to an improvement in wringers, and particularly to that class in which the pressure on the rolls is applied by means of U-shaped spring journal hangers 0r arms.

The object of my invention is to provide simple and convenient means for forcing the rollers apart when desired or necessary, the construction and operation of which will be fully setforth in the following description of the accompanying drawings.

Figure l is a front elevation of the clotheswringer to which my invention is applied. Fig. 2 is a transverse sectional elevation on line x w,

Fig. l. Fig. 3 is an inside elevation of one of my gage or shield plates. Fig. 4 is a longitudinal elevation of the lower roll, one end being in section, in connection with avertical central section of the shield-plate.

A represents the customary clamp bed-plates of the wringer. l

B B are the rolls, which are supported in journals attached to the ends of the U-shaped spring-hangers C. v

D represents end shields or gage -plates, which are provided with slots, as shown, and through which slots pass the axial shafts of the lower roll, B.

b represents the journal-bearings in the shield-plates D for the axial shafts of the upper roll, B.

E E represent right and left taper screwthreads, and e a collar or washer at both ends of the lower roll for holding the rubber F of the roller in position against lateral strain.

These lianges and screw-threads maybe made integral with the shaft G, as shown in Fig. 4; or they may be made of sleeve form, and be keyed or brazed to said shaft.

H represents a slot in each of the shieldplates D, in which rests the journals or gudgeons of shaft G. The edges of slot H are rounded, or made sufficiently pointed to lit into the grooves of screw-threads E.

The operation is as follows: Plates D rest loosely upon the shafts of the rollers B B, and are normally in the position shown in Fig. 4, in the sectional part thereof, and remain in this position only as the shaft is turned forward, or in the direction for wringing clothes. When it is desired to release the pressure, crank I is turned backward, when the screw-threads E on the journals of the shaft G engage with the edges of the slots H, drawing the lower ends of the plates inward, and elevate the plates D, and with them the upper roll, B', a distance corresponding to the incline -of the taper threads E. Vhen it is desired to apply pressure, a reverse motion of the crank carries the parts back to their normal position under the spring-pressure of the journal-hangers.

I claim- In a clothes-wringer, the combination, with the spring-hangers C, and rolls B B', having their shafts supported by the hangers, the shaft of one being provided with taper reversed screwthreads E, ofthe plates D, provided with rounded or knife-edge slots H for the passage and operation of roll-shaft G, substantially as and for the purpose specified.

In testimony whereof I have hereunto set my hand.
